VALVE AND ELBOW FOR HOT-WATER RADIATORS.

SPECIFICATION forming part of Letters Patent No. 563,120, dated June 30, 1896.

Application filed March 5, 1896. Serial No. 581,884. (No model.)

To all whom it may concern:

Beit known that I, OURT J. BALTHASAR, of New York city, New York, have invented an Improved Valve and Elbow for Hot-Tater Radiators, of which the following is a speciiication.

This invention relates to a valve and elbow forhot-water radiators which is so construted that by it the proper connection between the radiator and the hot-water-circulating pipes may be effected in a quick and simple manner.

In the accompanying drawings, Figure lis a vertical section, partly in elevation, of my improved valve and elbow, showing it coupled to a radiator. Fig. 2 is a plan of the valve and elbow; Fig. 3, an end view of a modi iication; and Fig. 4, a side view, partly in section, thereof.

The letter a represents the casing of my improved elbow, the vertical leg of which terminates in two branches a' and a2. Of these, the branch a is by coupling b adapted to be connected to the riser b, while the branchv a2 is adapted to be connected by coupling c to the return-pipe c. Longitudinally through the elbow a there extends a diaphragm d, which divides the elbow into the inlet e and the exit f, of which the inlet communicates with the riser b,while the exit communicates with the return-pipe c. A valve g, extending into passage e, controls the iiow of hot water into the radiator. lThe horizontal branch of the elbow a is provided at a distance from its end with a threaded section CL3, which screws into the rst loop A' of the hot-water radiator A, so that the end of the elbow projects transversely across said loop. The lower or exit passage f of the elbow is open at its end and communicates directly with the lower chamber A.2 of the radiator. The upper or inlet passage e of the elbow, however, is closed at its end by a wall e' and is perforated in frontA of such wall, as at e2, so that the inlet eis put into communication with the loop A', but out of communication with the chamber A2. Thus it will be seen that by simply coupling the elbow to the radiator and to the pipes b c the proper connection is at once eected in a most simple manner, and that not only a multiplicity of connections but a tedious fitting of the parts is dispensed with.

The circulation is as follows: from riser b and passage e through perforation e2 into the first loop A', thence through chamber A3 and loopsA4'to chamber A2, and thence through outlet f to return-pipe c.

In Figs. l and 2 the branches a a2 of the elbow are shown to be placed side by side, fi. e., in the plane of the radiator. In Figs. 3 and 4 they are shown to be placed in front of one another, 1l. e. in a plane at right angles to the radiator. arrangement of parts is the same as that previously described.

What I claimuisl. A valve and 'elbow forhot-water radiators composed of i, al casing, a longitudinal diaphragm extending therethrough to form inlet and outlet passages, of which the inlet-passage is closed at its horizontal end and provided with a discharge-orifice in front of such end, and with a valve within the casing, substantially as specified.

2. A valve and elbow for hot-water radiators composed of a branched casing, a longitudinal diaphragm extending therethrough to form inlet and outlet passages, a threaded section on the casing at a distance from its discharge end, and a regulating-valve, all being so constructed that the inlet-passage is closed at its horizontal end and perforated in front of such end, while the outlet-passage is open at its horizontal end, substantially as speciied.
